... the electromagnetic force to suspend the rotor, and there is no mechanical contact between the rotor shaft and the stator. However, the magnetic bearing technique requires additional electromagnetic parts in the motor, leading to the use of extra core and windings and to a longer motor axial length. Therefore...

...W.‐R. Canders; H. May; R. Palka The paper presents different topologies of inherent stable magnetic support systems consisting of monolithic high temperature superconductors (HTSC) and permanent magnets (PM). They may be used as contactless magnetic bearings for high speed rotating machines...
